全球变暖原因英语作文范文（热门20篇）

I often see on television, network is now the holes of the earth has been destroyed by human, if we are in different heart to protect it, the destruction of the earth will be completely in the near future. Faster and faster, with the development of human science and technology science and the negative effect gradually manifested, then let me give you a few examples to illustrate why experts predicted that the earth will be gone after so many years.

First of all, global warming is one example, soak in the hot weather in summer air conditioning becomes a new "hobby", but what do people ever thought of air conditioning can bring negative effect? Gas air conditioning to contain large amounts of methane, to the outside is the leading cause of global warming gases, methane and air conditioning will waste a lot of electricity, so try to avoid using the air conditioning or appropriate use.

Another reason is that carbon dioxide, automobile exhaust and factory waste gas containing a large amount of carbon dioxide, and carbon dioxide are most likely to lead to global warming. Cars now, too much exhaust serious affect our nong cough, throat inflammation... . According to concerning sectional statistic Chinese per capita emissions of carbon dioxide emissions 2.51 tons each year. The changes in the harsh environment around us.

More important reason is that: reduce forest, farmland, water damage and serious water pollution, fresh water supply is a problem, many parts of the draft has become a big problem. Now countries are massive effort, demanding, and costs "of the south-north water diversion project".

In order to save the planet, people all over the world should be: dont open air conditioning, use recycled environmental protection bags, dont use plastic bags, take the bus, dont throw waste batteries... Such as the dribs and drabs in life. In fact, environmental protection is not difficult, as long as you support is the best gift you give earth environmental protection, take action, this is a powerful force!

我在电视上、网络上经常看到现在的地球已经被人类破坏的千疮百孔，如果我们在不同心协力的保护它，地球将在不久的将来彻底的毁灭。随着人类科技的发展越来越快，科学随之产生的负面影响逐渐体现出来，下面我就给大家举几个例子来说明为什么专家会预言地球将在多年后不复存在。

首先全球变暖就是一个例子，天气炎热在酷暑里泡空调成为一项新的“业余爱好”，但人们可曾想过空调会带来什么负面影响呢?空调排出的气体中含有大量的甲烷，输送到外面甲烷也是导致全球变暖的气体，同时空调还会浪费掉大量的电力资源，所以要尽量避免使用空调或适当使用即可。

另一个原因就是：二氧化碳，汽车尾气与工厂废气中含有大量二氧化碳，而二氧化碳最可能导致全球变暖。现在汽车逐渐增多，太多的尾气严重影响着我们咳嗽、喉哝发炎……。据有关部门统计中国每年的二氧化碳排放量人均排放量达到2.51吨每年!我们周围的环境在恶劣的变化。

更重要的原因就是：森林减少，农田减少，水资源破坏，水污染严重，新鲜的淡水供应成了问题，许多地方吃水已经成了一大问题。现在国家也在大规模的搞费力，费神，又费财的“南水北调的工程”。

为了拯救地球，全世界的人们都应该做到：不开空调，使用回收环保纸袋，不用塑料袋，乘坐公交车，废旧电池不要乱扔……等生活中的点点滴滴。其实环保并不难，只要大家支持环保就是你给地球最好的礼物，行动起来吧，这就是一股强大的力量!

我读完《全球气候》时，我才发现环境的严重污染。

I read the "climate", I found that the serious pollution of the environment.

里面说，现在由于二氧化碳的严重增多，导致全球变暖，从而影响海平面上升0。5厘米。听起来不算多，可是地球上还有更大的淡水区，那就是南极和格陵兰岛，如果南极的冰全部融化，海平面会上升60米，再加上格陵兰岛的冰，海平面还会上升6米。现在的美国海边，经常有台风出现，导致巨大的经济损失，气候变暖使高山动物开始迁移，许多动物因为不适应环境而灭绝。

It said, now due to carbon dioxide more serious, leading to global warming, sea level rise and influence 0. 5 cm. This may not sound very much, but the earth has more fresh water area, it is the Antarctic and Greenland, if all the melting of Antarctic ice, the sea level will rise 60 meters, plus the Greenland ice, sea level will rise 6 meters. Now America beach, often have typhoon occurs, resulting in huge economic losses, due to climate warming in Alpine animal migration began, many animal extinction because they do not adapt to the environment.

所以我们要积极响应“保护环境，人人有责”的号召。

So we should actively respond to "Protect environment is everyones responsibility," the call.

Many people believe that human activity is causing the earth’s temperature

to rise. They say that this global warming will have dreadful consequences for

our environment, such as drought and flooding.

What should governments do to help prevent global warming? Give reasons for

your suggestions.

The earth’s temperature is rapidly changing. As a result there has been a

lot of climate change such as heat waves, droughts and floods. Scientists

believe that this is the result of human activity, which is polluting the

Earth’s atmosphere. This could become a disaster if governments do not act to

help prevent global warming. They can act in three ways; by supporting research,

by making laws and by keeping the general public informed.

Firstly, governments can support research. For example, they should

encourage companies to develop vehicles that cause less pollution. They should

also support alternative sources of electricity from wind and water rather than

from oil and coal. As well, they should sponsor conferences to discuss the

effects of greenhouse gas emissions and possible solutions to the problem.

Secondly, they should make laws that limit the amount of greenhouse gases

that companies can emit. Private companies should be rewarded for following

these laws. They should also be punished for creating pollution.

Finally, everybody is affected by global warming. Therefore, it is

important that governments involve individuals in the problem solving process.

For example they should encourage households to save as much energy as possible

by using more efficient light bulbs or less hot water. They should also

encourage the public to recycle, and this should be compulsory for everyone.

Another way of saving energy is by public transport systems. Governments should

spend money on public transport to make it as easy as possible for the public to

save energy.

In summary, it is clear that there are a lot of things that governments can

do to prevent global warming. They should involve companies, support scientists

and encourage individuals to protect the planet.

The Cause of fire

As we all know, fire is one of the most terrible killers in our modern society.We know that fire is mainly caused by smokers, followed by defective insulations and children playing with matches.In 2002 ,thousands of fire happened all over the country, of which 50 percent was caused by smokers who left cigarette-ends everywhere.Those who smoke should make sure that the cigarettes are stubbed out before being thrown away.Also, smoking should not be allowed in public places.30 percent of fire was caused by defective insulation. Workers should know the importance of good insulation for people’s lives.At homes we must pay special attention to electric wires and make sure that they are safe.20 percent of fire are caused by children playing with matches. We should warn children of the danger of playing with matches.

No matter what type of the reason it was, there was one thing in common:carelessness.So if everyone in the country is careful enough, more fire could be avoided.

我们都知道火灾是现代社会最可怕的杀手之一。火灾主要是由吸烟者、绝缘不良和孩子玩火柴引起的。在2002年，全国发生了成千上万起火灾，其中50%是由于吸烟者随便扔烟头引起的。那些吸烟者应该在扔烟头前确保烟头已经被掐灭。而且，公共场所应该禁止吸烟。30%的火灾是由于绝缘不良引起的，工作人员应该懂得绝缘对人们的重要性。在家里时我们应该尤其注意电线，要确保它们的安全性。20%的火灾是由于孩子玩火柴引起的，我们应该警告孩子玩火柴的危险性。

不管是哪种类型的原因，它们都有一个共同点：粗心。因此如果国家中每个人都足够细心，那么更多的火灾是可以避免的。

寒冷的冬天过去了，可今年冬天连一场雪也没下，天气也不怎么冷，为什么会这样呢?

The cold winter has passed, but this winter with snow is not, is not how cold the weather, why is this so?

我问了妈妈，妈妈说：“我也不太清楚，你去网上查查吧。”我打开电脑，输入——为什么全球气候变暖。版面上出现了许许多多的答案。

I asked my mother, my mother said: "I dont know, you go online to check." I opened the computer, input -- global warming. There have been many answers on the layout.

因为人类毁坏森林并将其焚烧时产生的多种温室气体，由于这些温室气体对来自太阳辐射的可见光具有高度透过性，而对地球反射出来的具有高度的吸收性，能强烈吸收地面辐射中的红外线，也就是常说的“温室效应”。导致气候变暖的后果，会使全球降水量重新分配，冰川和冻土消融，海平面上升等，危害自然生态系统的平衡，人类的食物供应和居住坏境。

Because of human destruction of forests and other greenhouse gases from the burning of when, because these greenhouse gases with high transmittance in the visible light radiation from the sun, and the earth is reflected is highly absorbent, can strongly absorb infrared radiation on the ground, the greenhouse effect is often said that the "". Global warming may lead to consequences, will lead to a global redistribution of precipitation, melting glaciers and permafrost, rising sea levels, damage the balance of the ecosystem and the human food supply and living environment.

全球变暖不仅危害了人类，而且还危害到动物的生存。比如说北极熊吧，因为全球变暖，冰川融化，北极熊捕食鱼类更困难，而且冰川急速融化，这样下去，北极熊这个物种早晚会灭绝的，跟北极熊一样的动物还有：北极狼，北极狐，企鹅。

Global warming is not only harmful to humans, but also endanger the survival of animals. For example, the polar bear, because of global warming, melting glaciers and polar bear hunting fish more difficult, and the ice melting fast, this continues, sooner or later the polar bears extinct species like the polar bear, Arctic wolf, Arctic animals are penguins.

想要阻止全球变暖，我们应该节约每一滴水;多种植数木减少沙化;不要再用一次性方便袋;减少二氧化碳的排放。我呼吁：为了我们的家园，我们一起行动吧!

Want to stop global warming, we should save every drop of water; plant more trees to reduce desertification; do not use disposable convenient bag; reduce the emission of carbon dioxide. I appeal to our homes, we act together now!

China has already begun to face an aging population. It is reported that by 2003 in China, the population over 65 years of age the proportion of the total population will reach 7%, which will allow China into the United Nations in 1956 set the population aging countries in the world. By 2020, this proportion will be increased to 10.85%, while in 2050, it will reach 20.43%.

At present, the time being will not become the worlds largest country in the elderly population. However, it is the process of aging faster than any other developing country. In fact, China will become the worlds population, one of the fastest aging process, this change brought to China unfavorable factors, it needs China to take a unique way to take care of the aging population.

Respect for the elderly project

In recent years, Chinas economy developed rapidly, with the strength becomes stronger, the state since 1990, security expenses for the elderly are more than 100 billion yuan every year, but also the state was increasing year after year, while also encouraging social and personal fund-raising, donations of non-juvenile welfare facilities set up to address a number of elderly people a sense of security, old age care issues. However, for a big country like China, but also there are other ways to those who need help to provide assistance for lonely elderly people. Care in the community, a warmth of respect for the elderly project in China, the rise of many young people took part in respecting the obligation to engineering work, they not only raised in all directions to bring the material assistance to the elderly, but also for their daily needs and get a wide range of help, thus bringing the warmth and love dedicated to the lonely and helpless old man.

This shows that the "senior citizen project," is Chinas aging population on the eve of a large number of old age to solve the problem of looking into a way to have multiple meanings, which not only brought the Gospel to the lonely elderly, but also carry forward the socialist spiritual civilization.

带翻译：

中国已经开始面临人口老龄化。据报道，到2003年，中国65岁以上人口占总人口的比例将达到7%，这将使中国在1956年联合国世界上人口老龄化国家。到2020年，这一比例将上升到10.85%，而在2050年，它将达到20.43%。

目前，暂时不会成为世界上最大的国家的老年人口。然而，它是一个过程，老化速度比其他发展中国家。事实上，中国将成为世界上人口老龄化最快的一个过程，这一变化将对中国不利的因素，它需要中国采取一种独特的方式照顾老年人。

尊重老年人的项目

近年来，中国经济发展迅速，与实力强大了，国家自1990年以来，安全费用为老年人每年超过1000亿元，而且该州增加了年复一年，同时也鼓励社会和个人募捐，捐款福利设施的设置来解决很多老年人一种安全感，老年护理的问题。然而，对于像中国这样一个大国，但也有其他方面需要帮助的人提供帮助孤独的老人。社区内照顾，温暖的尊重老年人的项目在中国的崛起，许多年轻人参加工程工作尊重的义务，他们不仅提高了四面八方，将材料帮助老人，而且对他们的日常需要和得到广泛的帮助，因此带来的温暖和爱献给孤独和无助的老人。

这表明“老年人项目，“是中国老龄化的前夕，大量的老来解决这个问题的调查方法有多个含义，这不仅给孤独的老人带来了福音，同时也弘扬社会主义精神文明。

After investigation, we found that caused the main reason for the increase of greenhouse gases is human activity. Carbon dioxide, for example, before the human society to realize industrialization in the early 19th century, the concentration of carbon dioxide in the atmosphere to 270 parts per million, and in 1988 to rise to 350 PPM. Atmospheric co2 concentration increased there are two main reasons: first, the dramatic increase in population and the development of industrialization, human society, consumption of fossil fuels has increased dramatically, combustion produces a large amount of carbon dioxide into the atmosphere, increase the concentration of carbon dioxide in the atmosphere: second forest reduces the amount of carbon dioxide absorbed by plants use, a speed reduction in carbon dioxide is consumed, also leading to higher concentration of carbon dioxide in the atmosphere. Greenhouse gases than carbon dioxide, such as methane, CFCS (freon), nitrogen oxide and so on also need to increase a different level.

Although there are many uncertainties, it is clear that global warming on climate, rainfall, and the influence of sea level and the resulting impact on human settlements and the ecosystem is extremely complex, must be given the attention they deserve. Think this kind of influence is irrelevant in the long run view is irresponsible.

The main cause of global warming, the atmosphere is destroyed, serious pollution and greenhouse effect caused by global warming could affect global warming will bring to the earth and human complex potential impact, both positive and there are also negative. Such as temperature height, deputy polar regions may be more suitable for human habitation, under appropriate conditions, higher co2 concentration can promote the photosynthesis, which plants have a higher rate of carbon sequestration, lead to the increase of plant growth, namely the stimulation effect of carbon dioxide, which is the positive impact of global warming. But compared with the positive impact, the negative impact of global warming on human activity will be more vast and far-reaching.

经过调查，我们发现引起温室气体增加的主要原因是人类活动。以二氧化碳为例，在人类社会实现工业化以前的19世纪初，大气中二氧化碳的浓度为270ppm，而到了1988年以上升到350ppm。大气中二氧化碳浓度增加的原因主要有两个：首先，人口的剧增和工业化的发展，人类社会消耗的化石燃料急剧增加，燃烧产生大量二氧化碳进入大气，使大气中的二氧化碳浓度增加：其次森林毁坏使得被植物吸收利用的二氧化碳的量减少，造成二氧化碳被消耗的速度降低，同样造成大气中二氧化碳浓度升高。二氧化碳以外的温室气体，如甲烷、氯氟烃(氟里昂)、氧化氮等也不同程度得增加着。

尽管存在着许多的不确定性，但显而易见的是，全球气候变暖对气候带、降水量以及海平面的影响以及由此导致的对人类居住地及生态系统的影响是极其复杂的，必须给以应有的重视。认为这种影响从长远来看是无关紧要的看法是不负责任的。

全球气候变暖的主要原因：大气层遭到破坏，严重的污染以及温室效应全球变暖可能造成的影响全球变暖将给地球和人类带来复杂的潜在的影响，既有正面的，也有负面的。例如随着温度的身高，副极地地区也许将更适合人类居住：在适当的条件下，较高的二氧化碳浓度能够促进光合作用，从而是植物具有更高的固碳速率，导致植物生长的增加，即二氧化碳的增产效应，这是全球变暖的正面影响。但是与正面影响相比，全球变暖对人类活动的负面影响将更为巨大和深远。

Recently, global warming has become a hot topic among people. It results from serious air pollution. As the environmental pollution is more and more strict, the temperature of all the world has dramatic increased. Gradually, some disaster such as drought, floodandGlaciers Melting follow. How terrible it is! Therefore, we need to protect our earth and fight against the disaster together.We should start from the trivial side. Making contribution to protecting our home.

近年来，全球气候变暖已成为人们关注的热门话题。它源于严重的空气污染。随着环境污染的日趋严峻，世界上的气温都急剧增加。渐渐地，一些灾害，如干旱，洪水和冰川融化接窘而来。多么可怕啊!我们要一起保护我们的地球和与灾难作斗争。我们应该从身边的小事做起。为了保护我们的家园作出贡献。

很多年以来，环境日益恶化。我们在提高生活水平的同时，也在导致环境污染。以下内容是小编为您精心整理的环境污染原因英语作文，欢迎参考！

环境污染原因英语作文一

The environment is everything around us,for example,air,water,animals,plants,buildings and so on.They all affect us in many ways and closely related to our lives.People cant live without the environment. Everybody needs to breathe air,drink water and eat food every day.We burn coal to keep warm,and we use wood to make paper.As a result,we become the part of the environment. The environment has been getting wores and wores for many years.We have been upgrading our living standard, meanwhile the environment has been polluted.Somke form factory chimneys pollutesthe air.Machines and engines make noises that annoy us constantly.Animals are homeless because the forcests are decreasing every minute.Streets are crowded with people and vehicles.The environment painful for us to live in it now.So its time to solve those problems.

Fortunately,it isnt too late to correct our mistake.People are coming to realiza the importance of the environment.We have begun to try our best to improve it.Laws are being made dealing with air, water and noise pollution.The river be bright,the sky will be clear,the flowers will be beautiful,and the sunbeam will be dazzling and pretty.We believe that we wil be able to save our environment and live in a better world

环境围绕我们身边，例如：空气、水、动物、建筑等。它们从各个方面影响着我们的生活，与我们的生活密切相关，人们离开环境就无法生存。每人每天都要呼吸、喝水和吃东西。我们少煤取暖、用木材造纸。结果，我们也成为环境的一部分。

很多年以来，环境日益恶化。我们在提高生活水平的同时，也在导致环境污染。从工厂烟囱里冒出来的烟污染空气；机器和引擎经常发出恼人的噪音。因为森林每分钟都在减少，使动物们无家可归。街道上挤满了人和车辆。环境在我们的生活中是最重要的，但是现在它已经让人们讨厌。所以，该是解决这些问题的时候了。

幸运的是，现在改正错误还不晚。人们意识到环境的重要性。我们已经开始尽力改善环境。法律也开始涉及到空气、水和噪音等问题。将来，河流会更清澈，天空会更晴朗，花朵会更鲜艳，阳光会更灿烂、更温暖。保护环境会使我们生活在一个更加美好的世界中。

环境污染原因英语作文二

With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends

与我们的生活水平的提高,越来越多的人都买得起汽车的。因此,道路往往没有堆满了汽车。然而,随着越来越多的废气排放是汽车、空气污染问题变得更加严重。所以现在我们提倡过低碳的生活。

我的建议是我们应该更经常骑自行车而不是开车骑一辆自行车,我们不仅能锻炼身体,也能保护我们的环境。为什么不试试,我亲爱的朋友

在这一则报导中，我学到很多事，但我第一个想到的是，造成地球变暖的原因是二氧化碳增加。

In this paper, I have learned a lot of things, but I think the first one is the cause of global warming, the increase of carbon dioxide.

为什么二氧化碳会增加呢?我想到的原因是人们常常开车、养食家畜、工厂大量排放黑烟……等。不过这些是大家可以一起解决，说不定可以改善地球继续暖化，例如：目的地很近的话可以骑自行车;目的地很远的话，可以搭乘公共交通运输工具;家畜的排泄物经过处理再排入河内;工厂可以建一座废弃处理厂……等。

Why carbon dioxide will increase? I think the reason is often drive, raising livestock, food factory emissions of smoke...... Etc.. But these are all can solve them together, it can improve the Earth continues to warm, for example: the destination is close enough to ride a bike; destination long enough, can take the public transport; waste livestock treated and then discharged into the Hanoi factory; to build a waste treatment plant...... Etc..

请大家不要小看二氧化碳的威力，等到海平面上升、都市浸水和农地淹没，到最后就会面临粮食不足的危机了。请大家跟我一起喊：“停止伤害地球的行为吧!我们居住的地球只有一个。”

Please do not underestimate the power of carbon dioxide, when the sea level rise, urban water and farmland submerged, eventually facing food shortage. Please call with me: "stop the harm to the earths behavior! Only one earth on which we live. "

Today is Saturday. Today is very strange, very special, because when I go

online today, an unexpectedly found a note, tonight at 8-9: to earth hour,

really depressed.

Then after I know detailed understanding of earth hour is what meaning,

which requires us out all the unnecessary lighting, achieve energy conservation

and emission reduction, global warming, improve the environment effect. Really

is a joke.

To improve the earth - our homes and not so easy. An hour out unwanted

light can achieve? Not that things are not so simple. Want to save our beautiful

home, must pay more attention to the ecological environment and save the earth

is not a moment to achieve.

I hope some and some of our homeland enterprises can give their hand.

When global warming, the world have changed dramatically.

The Antarctic ice and snow melt, human feeling will be under water, it is human to take the consequences. Arctic overlord, the polar bear also gradually extinction due to global warming. Has been the mother to a pair of scissors to bear, baby bear curiously ask: "mother, with scissors stem what ah?" Mom replied in a tone of command: "quick shearing, longer so thick hair will be hot dead!" Naive to bear looked at his mom, "we live in the ice and snow, how can heat? This is our coat, without it will be cold, cant cut!" Mother bear tone with a sad and sigh: "global warming, in does not adapt, now Im afraid go!"

Global warming, the polar bear cant find food, even little bear, it is be compelled helpless! Humans shall make profound reflection to your behavior, but, when global warming, human couldnt realize his mistake! Only know no longer suffer from the cold in winter, the temperature rose, the cold has gone, only the immediate interests, didnt know that will be far away from the white snow, originally should be open the flowers in the winter.

When global warming, I hope this to human consciousness already consequences. Early up, to stop all this happen!

当全球气候变暖时，世界发生了巨变。

南极，冰雪融化，人类感觉将要处于冰水之中，这是人类自食其果。北极的霸主北极熊，也因全球变暖而逐渐走向灭绝。一直熊妈妈向小熊递来一把剪刀，熊宝宝好奇地问：“妈妈，用剪刀干什么呀?”妈妈以命令的语气回答：“快剪毛，再长这么厚的毛会被热死的!”小熊天真的望着妈妈：“我们住在冰天雪地里，怎么会热呢?这是我们的外衣，没有它会受冻的，不能剪!”熊妈妈的语气中带点悲伤和叹息：“现在全球变暖，在不适应，恐怕就走向灭亡了!”

全球变暖，北极熊无法找到食物，甚至食用小熊，这是被逼无奈呀!人类应当对自己的行为进行深刻的反省，可是，当全球变暖时，人类还无法意识到自己的错误!只知道冬天不再受寒风的折磨，温度上升了，寒冷已离去，只顾着眼前利益，可不知道以后将远离那洁白的雪，原本应在寒冬中开放的花。

当全球变暖时，希望人类早已意识这以后果。趁早弥补，阻止这一切的发生!

Earth’s temperature begins with the Sun. Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbed solar energy heats our planet.

地球的温度开始太阳。大约百分之30的太阳光被反射回太空的光明面与云冰。在余下的百分之70，多数是由陆地和海洋吸收，其余的被大气层吸收。吸收太阳能加热我们的星球。

As the rocks, the air, and the seas warm, they radiate “heat” energy (thermal infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbed by water vapor and long-lived greenhouse gases such as carbon dioxide and methane.

当岩石，空气，和温暖的海洋，他们辐射热能源(热辐射)。从表面上看，这种能量进入大气层，大部分是由水蒸气和长寿命的温室气体如二氧化碳和甲烷的吸收。

When they absorb the energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight.

当他们吸收辐射能量从地球表面，微观水或温室气体分子变成小加热器-就像在壁炉的砖，他们散发热量，即使在火熄灭。他们在所有方向辐射。能量辐射回地球加热低层大气和表面，增强他们从阳光直射加热。

This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.

这种吸收和辐射热的气氛自然温室效应有利于地球上的生命。如果没有温室效应，地球表面的平均温度将是一个非常寒冷的18°C(0°F)而不是舒适的15°C(59°F)，它是今天。

Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.

很多人都认为是人类活动导致了全球气温上升。他们说全球变暖会对我们的环境造成可怕的后果，如干旱和洪水。

What should governments do to help prevent global warming? Give reasons for your suggestions.

政府该做什么来防止全球变暖呢?给出你建议的原因。

The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.

地球的温度正在迅速改变。导致很多气候变迁，如热浪、干旱和洪水。科学家认为这是人类活动污染了地球的大气层的结果。如果政府不采取行动来防止全球变暖的话，这可能会成为灾难。他们可以在三个方面上有所行动;支持研究，制订法律和保持公众知情。

Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.

首先，政府可以支持研究。例如，他们应该鼓励公司致力于汽车研发来减少污染。他们也应该支持来自风和水的电力替代能源，而不是来自石油和煤的电源。同时，他们应该主持会议来讨论温室气体排放的影响和可能解决问题的方案。

Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.

其次，他们应该制定法律限制公司发出的温室气体。私人公司应该因为遵循这些法律而得到奖励。他们也应该因为创造出污染而受到惩罚。

Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.

最后，每个人都是受到全球变暖的影响。因此，政府和个人在解决问题的过程中是很重要的。例如，他们应该鼓励家庭尽可能多的节省能源，尽可能多的使用更高效的灯泡或少用热水。他们也应该鼓励公众回收，因为这对每个人来说都是必须的。另一种节约能源的方法是公共交通系统。政府应该把钱花在公共交通使公众尽可能容易的节约能源。

In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.

总之，很明确的，各国政府可以做很多事情来防止全球变暖。他们应包括公司，支持科学家和鼓励个人保护地球。

As the development of the society, people want to conquer the environment,

they use the high technology to change the environment, when people are

satisfied with what they did to the nature, the nature is starting to teach

human being a lesson. In the movie The Day After Tomorrow, people were in the

great disaster that caused by the greenhouse effect, it just like the end of the

world, there was no way for people to avoid such great disaster. The movie

reminds people of the result they did harm to the environment, it will revenge

people, people have to face the disaster. It is very important to protect the

environment, people should get along with the environment.

老龄化现象The Aging Phenomenon

The Family Plan has been adopted for several years, most of the young generation are only child because their parents follow the government’s policy. Over more than 30years, most family are made up of grandparents, parents and a child. Here comes the problem, the society is facing an aging situation, more and more people are getting old while the young people are less. For a typical family, four grow-ups are at the age of over 40 with a young kid less than 20years old. The aging society is getting more and more obvious, such phenomenon has been catch mass media’s attention.
